IPA: //ˈmɛzəˌkɑrp//
KK: /ˈmɛzəˌkɑrp/
The middle layer of a fruit's outer covering, which is often soft and fleshy.
The mesocarp of the peach is the juicy part that we eat.
Mesocarp → It is formed from "meso-" (from Greek "mesos", meaning middle) and "carp" (from Greek "karpos", meaning fruit). The word "mesocarp" refers to the middle layer of the pericarp, which is the part of a fruit between the outer skin and the inner seed.
Think of the 'middle' ('meso-') layer of a fruit ('carp') — that's what mesocarp refers to.
